A Leapfrog in Additive Manufacturing

The emerging field of nanoscience and technology, highly valued in China, is witnessing a significant leapfrog with the development of micro-nano 3D printing technology. By manipulating materials at the nano-scale, scientists can now create objects with unprecedented accuracy and complexity, expanding the horizons for additive manufacturing and promising further innovation and research in the future.

Building Human Organs on a Chip with Micro-Nano Robots

Researchers from Shanghai Jiao Tong University have taken this technology to new heights by developing a multi-stage delivery strategy of magnetically controlled micro-nano robots. Utilizing a human organs on a chip (OOC) model, they have successfully constructed a hierarchical vascularized OOC that accurately replicates the structure and function of different organs in the human body. With the aid of micro-nano 3D printing technology, these scientists can infuse magnetically guided micro-nano robots into these OOCs and navigate them inside blood vessels using an external magnetic field.

Applications Beyond Imagination

The applications of these vitro models are vast, including facilitating drug screening, reducing the cost of drug research, and enhancing the efficiency of drug development. Moreover, these micro-nano robots could play a crucial role in medical treatment, such as building a vitro OOC for a tumor patient. This could serve as a substitute for the patient to try different drugs and guide clinical medication, showcasing the potential of micro-nano 3D printing in the realm of personalized medicine.
